ARTEMUS IVELSII, OF LAWRENCE, KANSAS, AND BRADY S. RICHARDSON AND ELMER \VELSI'I, OF SOOTTDALE, PENNSYLVANIA.

SPIKE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 424,586, dated April 1, 1890.

Application filed July 6, 1889. Serial No. 316,722 (No model.)

To aZZ whom it may concern.-

Be it known that we, ARTEMUS \VELSH, of Lawrence, Douglas county, Kansas, and BRADY S. RICHARDSON and ELMER WELsH, citizens of the United States, residing at Scottdale, in the county of lVestmoreland and State of Pennsylvania, have invented a new and useful Spike-Machine, of which the following is a specification.

This invention has relation to spike-niachines; and it is especially designed for the manufacture of a railroad-spike, the specific construction of which is shown in a patent granted us May 31,1887,No. 364,071, in which there appears a shank port-ion having a tapered entering end and a head portion combining certain formations designed for certain purposes fully explained in the said patent.

Among the objects in view are to provide an automatic machine into which is adapted to be fed a bar of metal and to provide mechanism which will receive said stock or bar, compress the same into shape to form the shank of thespike, automatically cut the same, and to provide opposite grippers the operative mechanism of which is so timed with relation to the shank-forming mechanism as to grip the unfinished spike at about the time or slightly in advance of the finish of its entering end and hold the same while a third mechanism is brought forward and against the advancing endof the spike for the purpose of forming a head.

A further object of our invention is to provide a machine havingmechanism described with certain detail mechanism constructed to produce a spike having the characteristics set forth in our patent above referred to.

WVith these general objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, F'gure 1 is a per- Fig. 2 is a rear end elevation of a machine constructed in accordance with our invention. Fig. 3 is a detail in transverse section of the compressing-rolls. Fig. i is a detail view of the cam 23.

Like numerals or reference indicate like parts in all the figures of the drawings.

1 represents the frame, which consists of the four opposite sides 2, provided with the bedplate 3. At the front of the machine, at each side thereof, are provided boxes 4, arranged in vertical line with each other, and in the upper pair is journaled a shaft 5 and in the lower pair a similar shaft 6. Upon the shafts 5 and 6. are mounted rolls 7 and 8, respectively, the peripheries of which are of a form to conjointly form the shank A of the spike. In this instance the roll 7 is provided upon its periphery with a series of four protuberances 9, each terminating in an enlargement 10, said enlargement corresponding with similar enlargements 11, formed in recesses 12, corresponding with the protuberances 9. From this it will be seen that a rod or bar B of iron subjected to the action of the two rolls, by being fed therebetween, will form the shank A, and by a space 13 formed between each of the projections 9, will form a blank head 0 upon the advancing end of the shank A, and when the enlargements 10 come in contact with each other the shank will be reduced, as at D, to form an entering end, and will be severed from the stock, all as clearly shown in Fig. 3.

Upon a transverse support 14, extending from the front to the rear portion of the bedplate 3, we mount opposite vertical guidingstandards 15 and a guiding-eye l6. Pivoted in the front ends of the standards 15, which are bolted to the support 14, is the header 17, through the upper end of which and passing into the standards is a bearing-pin l8.

19 represents a pitman, the front end of which is connected to the header 1'? at about its middle, the rear end of the pitman being connected, as at 21, to a cam-rod 22, extending from a cam 23, mounted on a shaft 24, extending transversely across the rear end of the machine and journaled in boxes 25, bolted to the machine and projecting from each side of the machine. Upon the shaft 2-l and outside of the boxes are mounted beveled gears 26. Beyond the gears the shaft is mounted in boxes 27, and is provided at opposite sides and beyond the frame 1 with beltpulleys 28, one at each side of the machine, and beyond the pulleys with crank-disks 29, which by crank pins 30 are connected to pitmen or driving-rods 31, the opposite ends the roll 8, which shaft 6 is also connected with the shaft 5 by gears 33 and 34:, mounted upon the upper and lower shafts, respectively. Opposite boxes 35 are provided at each side of the bed-plate 3, and in the same are mounted opposite shafts 36, which at their rear ends are provided with beveled gears 37, arranged at right angles to and meshing with the bevels 26. The front ends of the shafts 36 are provided with cams 38, upon which are mounted cam-rings 39, provided with inwardly-projecting cam-rods 40, the inner ends of which are supported and guided by suitably-grooved bolsters 41. The cam-rods 40 are of a relative length to nearly come in contact with each other when the cams 38 are in an inwardly-disposed position. The inner ends of the cam-rods 40 are provided with grippers 41 having recesses 42, of a shape adapted to form the enlargement E and shoulders F of the spike. By a suitable proportioning and timing of the mechanism described these grippers described are brought forward to grip the spike in rear of its advancing end or that portion which is to be subsequently upset to form the head exactly when the opposite projections 10 and 11 meet and separate the unfinished spike from the stock B. At the same that the grippers close upon the shank the rolls are inactive and the header 17 is swung forwardly and upsets the advancing end of the unfinished blank against the sides and into the recesses 42 of the grippers. The header is provided with facial depressions for the purpose of forming the head of the spike inv the manner shown in our patent.

The operation of our invention will be at once apparent, but may be briefly stated as follows: Motion is imparted from any suitable motor through belts to the pulleys 28, which revolve the shaft 24, and through the cam 23 and the rings and itsrod a reciprocatory motion is imparted to the pitman 19, which by reason of its pivotal attachment to the header 17 and its pivotal mounting in the standards 15 said header is swung forward and performs the function described of upsetting the metal to form the head of the finished product. As the shaft 24 rotates, it through the medium of the gears 26 imparts motion to their respective gears 37, from thence to the shafts 36 and to the cam 38, which through the medium of their cam-rings 39 imparts reciprocatory motion to the cam-rods or plungers 40, which carry the grippers 41. As the shaft 24 rotates the crank-disks 29 are likewise rotated, and with them the rods 31 are reciprocated, which rotate the shaft 6, and from the shaft 6 motion is imparted to the shaft 5 through the medium of their respective gears 33 and 34.

We do not limit our invention to the employment of the exact form or facial contour of the header 37 or the grippers 41, as they may be varied in accordance with the special construction or form of head and shank desired. So, also, the rolls 7 and 8 may be provided with peripheries differing from those herein described for the purpose of forming shanks of any desired contour. The starwheels are in this instance four, pointed to agree in number and location with the projections 11 on the roll 8 and the corresponding projection 10 of the roll 7. As the crankdisks 29 revolve the pitman takes into one of the points of the star and gives the two rolls a comparatively sudden and forcible pull, so that said rolls may quickly sever the blanks, or rather the unfinished spike, from the stock. Said pull also serves to give impetus or momentum to the rolls to a sufficient degree to enable them to form the shank of the next succeeding spike and to continue the formation up to the point of cutting or severing the same from the blank. By this time by reason of the relative proportion of the pitman and crank-disk the free end of the pitman will be in a position to engage the next pair of points of the wheels. The wheels 32 are preferably formed in pairs, and the pitmen operate between a pair and are provided at their free ends with laterally-projecting pins 32 for engaging the points.

The guides 22 at each side of the cam 23 serve to guide the cam-rod 19, which projects at both sides of its cam.

Having described our invention, what we claim is 1. In a machine of the class described, a transverse power-shaft provided with a cam, in combination with a ring mounted on the cam and provided with a rod, a bearing for the rod, and a pitman pivotally connectedto the rod and having its opposite end pivotally connected with a swinging header at its lower free end, said header being pivotally mounted in opposite standards, substantially as speci fied.

2. In a machine'of the class described, a power-shaft and bearings for the same, opposite right-angularlydisposed shafts provided with beveled gears at one end meshing with similar gears on the power-shaft, and pro vided at their opposite ends with cams, camrings mounted on the cams and provided with cam-rods, and grippers mounted at the ends of the cam-rods and reciprocating in guides, in combination with a cam mounted on the power-shaft, a ring encircling the same,a rod extending from the ring, a pitman pivoted to the end of the rod, and a vertically-swinging header pivoted at its upper end to suitable supports and having its lower end pivotally connected with the other end of the pitman, the mechanism being so timed that the grippers advance prior to the swinging of the header, substantially as specified.

3. The combination, with the rolls 7 and'S and their shaft-s 5 and 6, of the opposite pairs of star-wheels 32 and the loosely-connecting pitman 31, substantially as specified.

4. The rolls? and 8, mounted on their shafts 5 and 6, respectively, and provided with the reg TIQ

registering projections 10 and 11, combined with the opposite pairs of star-wheels 32, mounted on the shafts, the points of the wheels agreeing in number and location with the projections 10 and 11, and the pitman having opposite pins 3?, engaging the points, sub stantially as specified.

5. In a spike-machine, the combination of a roll 7, having protuberances or webs 9, terminating in enlargements 10, the roll 8, having the recesses 12 and enlargements 11, the transversely sliding grip dies having recesses, as 42, and the swinging heading-die, in combination with mechanism for intermittently partially rotating the rolls and for moving the gripping-dies transversely toward each other and the heading-die forward in the direction of the rolls while the latter are stationary, substantially as set forth.

6. In a spike-machine, the combination of a pair of shafts geared together, the main shaping-rolls, mounted oppositely on said shafts, the star-wheels upon the ends of one of said shafts, the power-shaft arranged parallel to the r0ll-shafts and having a crank at each end,
